This Article develops the themes of history, language, and culture in the art of mixed jurisdiction impact analysis. It showcases a specific law (former article 177 of the Louisiana Civil Code) governing the liability of the building master for things thrown out of the house into the street or public road. Our case study gives real meaning to the Romanist mixité wrought into Louisiana's civilian core. The reader is not only invited to take a seat on the time machine for a journey through Louisiana's codal triad back to Roman law with stops in Medieval Spanish law and Pre-Napoleonic French law, but also encouraged to reflect on present-day alternatives for construing and applying the law.
